cell

7

who first used the term 'cell'

Robert Hooke

8

How did Hooke come up with the word cell

slice of cork, and what he saw reminded him of monastery cells where monks slept, empty chambers.

9

theory stated that all living organisms are constructed of small sub units called cells
two men

Cell Theory
- Schleiden and Schwann

10

4 basic types of tissue

2. connective tissue
3. muscle tissue
4. nervous tissue

11

tissue that lines something or a surface- skin, stomach lining

epithelial tissue

12

tissue that holds things together, extracellular matrix, cartilage

connective tissue

13

cardiac, skeletal smooth

muscle tissue

14

brain, neurons and associated glial cells.

nervous tissue

15

the smallest structural unit of living matter that can function independently in the proper environment

cell

16

'nut'

nucleus

17

'small nut'

nucleolus

18

a compound occurring in the liver and other tissues that inhibits blood coagulation.

heparin

19

a compound that is released by cells in response to injury and in allergic and inflammatory reactions, causing contraction of smooth muscle and dilation of capillaries.

histamine

20

credited with creating the first "histology" that was based on a detailed examination of tissues with the microscope

Henle
-"loop of Henle"
